The working principle of the Transmission Electron Microscope (TEM) is similar to the light microscope.The major difference is that light microscopes use light rays to focus and...
Raman spectroscopy is an analytical technique where scattered light is used to measure the vibrational
energy modes of a sample. It is named after the Indian physicist C. V. Raman who,...

مجهر القوة الذرية Atomic Force Microscopy هو التقنية المفضلة لرؤية جسيمات الحمض النووي DNA النانوية، ويقوم مجهر القوة الذرية بعمل قياسات كمية ثلاثية الأبعاد.
The Stern-Gerlach experiment had a profound effect on the scientific community in the early part of the twentieth century. In 1922 Stern and Gerlach
measured the possible values of the magnetic...
Suppose you want to run a marathon. A basic law of science called the conservation of energy tells us you need to fill your body with "42 km (26 miles) worth of food." Or say you...

Electric Potential
In the previous lecture, we’ve talked about*electric potential energy*which is dependent upon the charge of the object experiencing the*electric field. Now, we’re going to...
In this lecture we will learn about electric field, the properties of the electric field lines, and the superposition principle. You can watch the following video or read the written tutorial...
When capacitors are connected in series, the total capacitance is less than any one of the series capacitors’ individual capacitances. If two or more capacitors are connected in...
Difference Between Convex and Concave Lens
The lens is understood as a curved and transparent piece of glass or plastic, which focuses and refracts light rays in a certain manner. The...
